Frequently Asked Questions
How does text diff work?
Text diff uses algorithms to compare two texts character by character or word by word, identifying what was added, removed, or modified. Differences are highlighted with colors for easy visualization.
Can I compare code files?
Yes, the tool works with any text including code. It will highlight differences in code, comments, and formatting between two versions.
What's the difference between line-by-line and word-by-word diff?
Line-by-line compares entire lines, while word-by-word compares individual words. Word-by-word is more precise but can be more detailed.
Can I compare very large texts?
The tool can handle reasonably large texts. Very large files (over several MB) may take longer to process or may need to be compared in sections.
